Excavation of the DMT2 shaft continues in the Money Pit as Andrew reports the caisson has reached 137 feet. Craig Tester notes that once they pass the remains of the Hedden Shaft they should be in undisturbed ground until 145 feet. Gary Drayton scans the next bucket of spoils and gets a signal, and Peter Fornetti digs out a piece of metal similar to fragments that tested positive for gold earlier in the season. Craig says the piece will be run through XRF and dated. Work is then halted for several hours after the cable wraps around the stabilizer. The following day, the hammer grab is repaired and Andrew reports they are at 146 feet with the dig and 157 feet with the caisson. The team encounters puddled clay, the same material found by the Onslow Company in 1804 and by Blair and Chappell just before they drilled into the vault at 153 feet. Dense, heavy wood covered in puddled clay comes up next, bearing hand saw marks. Danny reports the casing has reached 174 feet with an additional five-foot section bringing the total to 191 feet. The caisson begins descending rapidly, but the hammer grab returns empty, and DMT2 is called.
On Lot 8, Gary and Michael John metal detect in search of artifacts that could help obtain permits for excavation of the anomalies found earlier by GPR scanning, and that might support Scott Clarke's theory connecting the rhodolite garnet brooch to the Knights Templar and the Ark of the Covenant. At the first flag, Michael unearths a piece of an old chain with an irregular shape that Gary says indicates it was handmade rather than factory produced. At the next flag they recover a large ox shoe. Gary suspects heavy loads were being hauled across the lot, given both the chain and the ox shoe.
At the wash table, Steve Guptill and Michael search the DMT2 spoils for clues. Steve finds what initially appears to be a fossil but turns out to be a piece of coal. Coal was used by European mining operations in underground furnaces to supply oxygen for workers, and the Onslow Company found puddled clay and charcoal when excavating the original Money Pit. Steve also recovers a piece of cement that will need testing.
In the War Room, Rick announces that Irving Equipment can place a fifth caisson, positioned one foot off EC1. Marty asks Scott Barlow to name the shaft, and Scott chooses B4-C. The team then connects by video conference with Corjan Mol, who presents evidence linking the Knights Templar and Portugal to Oak Island. Corjan notes that Portuguese artifacts have already been found on the island and explains that the Templars were dissolved in every country in 1312 except Portugal, where many knights fled under the protection of King Dinis. In 1319 King Dinis reconstituted the order as the Order of Christ and changed the logo. Corjan explains that the Order of Christ made maps during their voyages at sea and shows the team the 1502 Cantino Map, which depicts Newfoundland and Nova Scotia. He suggests that Templar archives in Portugal could contain documents connecting the order to Oak Island.
